MUSIC-LEAF TURNER.

' Application led August 20, 1921, Serial'fNo. 493,960.

To aZZ whom t may concern:

Be 1t known that we,` VALTER S. LUKAW- SKI and MICHAEL A. ZIELINsII,citizens of the United States, residing atChicago, in

the county of Cook and State of Illinois, have invented new and usefulImprovements in Music-Leaf Turners7 of which the following is aspecification.

This invention relates to music leaf turn# ers and an object of theinvention is to pro vide a music stand to permit the turning of theleaves of a boo-k of music or the pages of what is commercially known assheet. music `without requiring the use of the hands of the user,lpermitting' him to turn the music at the proper timel without in any yayinterrupting the playing of his instrument. e y

Another object of this invention is to provide a device as specifiedwhich can be collapsed and carried about in a relatively smallconveniently handled container thereby adapting the music stand for useby bandplayers or analogous musicians when playing` at different places.

A further object of this invention is toV provide leaf or sheet turningmeans which is operated by means of footlevers, for

Iturning the leaves or sheets of music and.

also to embody balancing means in said turning means to provide eventurning of the music and prevent undesirable noises during the operationof the device, and also to provide aA novel structure whereby the heightof the sheet carrying head of the rack may be regulated as desired forproperly `supporting music sheetsv of different lengths Other objects ofthe invention will appear in the following detailed description and inthe accompanying drawings wherein: W

Fig. l is a front elevation of the improved music stand and leaf turner;Fig. 2 is an enlarged rear elevation of the yhead of the stand showing aportion of the music holding frame or head showing the` turning arms Intheir normal position. y

Fig. ll is a detail section through a cushioning member embodied in themusic leaf turningstructure taken on the line ll--ll of Fig. l. Fig. l2is a detail view of one of the turning arms. `v

Fig. 13 is a section through the turning arm taken on the line 13-.13 ofFig. 12.

Fig. 14 is a detail section taken on 4the line 1.4 14 of Fig. l2illustrating the manner of connecting the sheets or leaves of music tothe turning arms.

Referring more particularly to the draw ing the improved music leafturner and stand structurel comprises a standard l vcomposed oftelescoping parts 2, 3, and 4 which may be telescoped one within theother to permit the stand to `be collapsedwhen not in use. The lower orbase section 3 of the standard l has a brace structure 5 adjustablymounted thereon and held in `position by means of a thumb screw `6which'eXtends through the sliding collar 7 to, which the brace legs 8are pivoted. The brace legs 8 are intfurn braced by diagonal braces 9which are pivoted to the lower end of the standard section 3. The musicframe or head structure l0 iscarried at the top of the section 4 and itcomprises an upper cross bar 1l and a lower cross bar l2 which areconnected at their ends by pivotal connecting bars 13 adapted to foldinwardly towards the axis of the stand lto permit movement of the barl2towards or from the bar 1l to permit variation of the .space betweenthese bars to accommodate .sheets of music of different lengths. Thebars 1l and l2 are preferably formed of .angle material as clearly shownin Fig. 8 of the ldrawings and the bar 11 has spring clips 14 connectedthereto adjacent its ends which are adapted to engage the backs of musicbooks or the cover and back sheets of sheet music and clamp themsecurely against the upper cross bar 1'1. The upper cross bar 11 has adownwardly extending bar 15 attached thereto which carries a socket 16on its rear surface to which the upper section 4 of the standard 1 isconnected. The bar 15 is positioned intermediate the ends of the bars 11and 12 and the latter bar is slotted as shown at k17 to permit the bar15 to extend therethrough which permits the angle bar 12 to slide up anddown vupon the bar 15 to permit reguylation Vof the distance between thebars 11 and 12. The lower bar 12 has an extension'18 formed thereon towhich a spring clip structure 19: is pivotally connected as shown at 20.The spring clip structure 19 may be of any approved form preferablycomprising a substantially vcylindrical spring member 20 which engagesthe gripping and operating members 21 forcing their gripping ends 22into binding engagement with the bar 15 to hold the bottoni bar 12 inadjusted positions upon the bar 15. lt will be seen from the foregoingdescription and Fig.7 of the drawings that an operator may easily andquickly adjust the position of the bai' 12 relative to the bar 11 byreleasing the clip structure 19 and when the clip structure is releasedthe bar 12 will be securely held in 'adjusted positions. If it is sodesired it is to be understood that the gripping A ends 22 of themembers 21 may have felt or analogous material attached thereto toprovide firm and nonslipping engagement with the bar 15 withoutvdeparting from the spirit of this invention.

v Leaf turning arms 25 are provided which are pivotally connected asshown at 26 to an extension 27 on the bar 11 and they are provided forturning sheets of music when necessary ywithout requiring theV use ofthe Each of the arms provided :with a segmental gear 29 which mesheswith rack teeth 30 on a sliding bar By -particular reference to Figures4 and 5 of the drawings it will be noted that the rack teeth 30 arearranged in sets 32,

the number of these sets corresponding tol the number of turning arms25. Owing to the factthat the arms 25 are disposed one against theother, it is necessary to position respective'sets 32 Von the raclrteeth 30 in laterally spaced relation and if it is so deL sired tosimplify and expedite manufacture, the bar 31 may be composed'of aplurality of bars 33 as clearly shown in Fig. 6 of the drawingsconnected for synchronous movement by means of rivets 34 which alsoextend through a suitableslot 35 formed in the substantially horizontalside ofthe bar 11.k The outermost of the bars 33 has an .angle extension36 formed thereon to which a link 37 is pivotally connected.' The linhthereto, the downward movement of which is limited by ears 42 cut fromthe lever 38 and bent `into the path of the arms 40 and 41. The arms 40and 41 have connection, by means of wires, cords or analogous flexiblemembers 43, to a bar 44 which is pivotally mounted, intermediate itsends as shown at 45, upon the bai' 15 preferably by means of the rivetor pivot 45 which is attached to the socket 16. The bar 44 is connected,Vby means of chains, wires, or analogous flexible devices 48, tofootpedals 49 and 50 respec-l tively, one of which is connectedto thebar 44 upon one side of its pivot while the other is connected to thebar upon the opposite side of its pivot as clearly shown in thedrawings, for rocking the bar in oppositeV folded upwardly along thestandard section 3 when it is desired to collapse the music stand andturner structure.

rlhe wires or flexible members 48 have shock absorbers or cushioningmembers 54 interposed in their lengths which are provided, incombination with the bar 44 to absorb abrupt action which might betrans-- mitted by the foot pedals to the operation and to insure evensteady operation of the turning arms 25 so as to eliminate undesirablenoises. Suitable cushions 55" are provided, which are carried by the bar11, to cushion the movement of the arms'and prevent noises during theiroperation.V Shockabsorber structures -54 are comparatively simple inconstruction comprising body shells 56 which are connected to thedownwardly extending portions of thewwires -48 and which slidablyreceive therein piston rods 57 which are connected to the upwardlyextending lengths of the wires 48. y The rods 57 have heads 58 upontheir inner ends against which cushion springs 59 engage. The cushionsprings 59 also engage` against an adjustable nut or head 60 which isadjustably carried by the body shells 56 and provides for regulating thetension of the spring 59..

The turning arms 25 are particularly constructed so as to readilyv adaptthem for movements to facilitate the attaching of Sheets of musicthereto, that is, each of the arms 25 is formed of a pair of sections 62and 63 pivotally connected as shown at 64. The section 62 carries a stoppin 65 which is engaged by a projection 66 on the section 63 to limitthe upward pivotal movement of the section 63 and by the end of thesection 63 to limit the downward pivotal movement of the latter. Thesection 63 has an enlarged head 67 on its free end to which a flatspring 68 is attached. The fiat spring 68 has a plate 69 of any suitablematerial, attached thereto to the inner surface of which a sheet 70 offelt or analogous material is attached for gripping a sheet of music andclamping it between the facing surfaces of the felt 70 and hea-d 67, thespring 68 acting to urge the felt 70 in engagement with the head 67. Inattaching a sheet of music to one of the turning arms 25 the music isproperly placed upon the music frame or head structure l0 and thesection 63 is swung upwardly after which the Spring 68 is movedoutwardly to space the felt 70 from the head 67 and the section 63 isthen moved to its normal position in alignment with the section 62 withthe sheet of music to be turned gripped between lthe felt 7 O and head67 after which the spring 68 is released and the felt 70 is forcedbetween the spring into firm clamping engagement with the sheet ofmusic.

From the foregoing description taken in connection with thelaccompanying drawing it will be apparent that a combined music leafturner and stand has been provided which is relatively simple inconstruction, one which will be efficient in its operation and may beoperated by a musician with his foot to turn the sheets of music asnecessary, without in any way interfering with 54 and bar 44.

It is, of course, to be understood that the invention may beconstruct-ed in various other manners and the parts associated indifferent relations and, therefore, we do not desire to be limited inany manner except as set forth in the claim hereunto appended.

Having thus described our invention what we claim is:

In a device of the character described, a rack including'upper and lowercross bars, a central bar having its upper end connected to the uppercross bar and means carried thereby whereby the lower cross bar isadjustably mounted thereon, said means comprising an extension formed onthe lower cross bar having an opening through which the central barextends, a spring clip having pivotal connection with theextension, saidspring clip including a substantially cylindrical spring member engagingthe arms of the clip, gripping ends adjacent the spring member adaptedto normally grip, the central bar and gripping and operating membersextending divergently from the gripping ends whereby to manipulate thegripping ends for adjusting the lower cross bar on the central bar.

In testimony whereof we aiiix our signatures.
